ANTITELESCOPING- DEVICE FOR RAILVAY-CARS.

Application filed October 25, 1911.

To all whom it may concern Be it known that I, ALBERT H. SIssoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Antitelescoping Devices for Railway-Cars, of which the following is a specification.

My invention relates to railway cars, and refers particularly to anti-telescoping means which are used for safety purposes in event of collision. Heretofore, when two cars have come into violent collision with each other it has often happened that the end sill of one car would rise above the end sill of the adjacent car, and thus the two cars would become telescoped.

It is the object of my invention to prevent this telescoping, and thereby reduce the disastrous consequences of collisions. I accomplish the desired result by using horizontally corrugated anti-telescoping devices rigidly mounted on the ends of the cars in rear of and in alinement with the respective bufier plates; and by making the buffer plates thin enough to be crushed between the inter-engaged rigidly mounted anti-telescoping devices of adjacent cars, so that the presence of the buffer plates does not interfere with the proper and effective operation of said antitelescoping devices, which when interengaged prevent the end sill of one car from riding; over the end sill of the adjacent car.

I prefer to employ a buffer mechanism which, in its general characteristics, is similar to the buffer mechanisms ordinarily en1- ployed for the well known purposes. The buffer plate which I prefer to use is of such construction that in case of a collision or unusual pressure between two adjacent cars the anti-telescoping members above-mentioned will become interlocked and thereby prevent the end sill of one car from rising above the end sill of the adjacent car.

These and other advantages of my invention will be more readily understood by reference to the accompanying drawings, in which- Figure 1 is a plan showing the ends of two adjacent cars with the bufier mechanism and anti telescoping device applied thereto; Fig. 2 is an end elevation of a p0rtion of a car, a portion of the buffer end plate and coupler being broken away. This view is taken on the line 2-2 of Fig. 1; Fig.

3 is a vertical longitudinal section, taken on the line 3-3 of Fig. 1; and Fig. 4 is a fragmentary vertical longitudinal section through the anti-telescoping devices and buffers of adjacent cars showing the antitelescoping devices in interlocked position.

On the end sills 10 of adjacent cars is mounted or integrally formed therewith the anti-telescoping members 11, which are pro vlded with horizontal projections 12, between which are the recesses 13. The conplers 14 are of the well known and usual type.

Each buffer consists of a frame 15, preferably consisting of an angle iron at the ends of which are the downward projections 16. Cooperating with the downward projections 16 are the spring-controlled buffer stems 17, of the usual type. Riveted to the front face of the frame 15 is the buffer front plate 18, which is preferably made of thin metal, while extending rearwardly from the frame 15 is the buifer top plate 19. Riveted to the end sill 10 is the tread plate 20, which projects over the buffer top plate 19.

It will now be evident that in case of a collision the buffers will be pressed inwardly, as indicated in Fig. 4, and each anti-telescoping member 11 will press against its corresponding buffer front plate 18, this plate being readily yieldable, the projections 12 of each anti-telescoping member 11 will be allowed to pass into a corresponding recess 13 in the anti-telescoping member of the adjacent car, and the buffer front plates 18 will be bent into appropriate positions. In this way the cars will be securely locked together, and danger of telescoping is effectually prevented.

It will be apparent to those skilled in the art that many changes could be made in the detailed construction of the parts which I have described without departing from either the spirit or scope of my invention.

What I claim is:

1. In a car construction, the combination of a car frame, a buffing mechanism, and an antitelescoping device rigidly mounted independently of the bufling mechanism, the buffing mechanism provided with means normally interposed between the anti-telescoping devices of adjacent cars but out of contact with the said devices but permitting them to engage and interlock upon collision, substantially as described.

dependently of the buffing mechanism, and a 'a shield'between but normally out of contact 2. In a car construction, the combination of a car frame, a bufling mechanism, and an anti-telescoping device rlgldly mounted 1nanti-telescoping device rigidly mounted independently of the bufling mechanism, and a plate movable With the buffing mechanism and adapted upon collison to be caught between the anti-telescoping devices of adjacent cars and deformed to permit the said device to interlock, substantially as deplate movable With the bufling mechanism as with the said devices and adapted upon collision to permit the interlocking devices of scribed. adjacent cars to interlock, substantially as ALBERT H. SISSON. described. Witnesses 3a In avcar construction, the combination E. H. LOUGI-IRIDGE, of a car frame, a buffing mechanism, and an ELENOR ORR.
